It is more specifically an object ofithe in The? vaginal duct of the sow is generally ventionto provide a pair of forceps having cirular inshape and asthepig's approach a flat blade with rounded ends as one of the 'deliyeryopeiiing theyshould be on thei'i jaws and a 'co-operatinghoolias the other bellies. It frequently happens;hew vei,

jaw which is bent toward said blade and that the pigs jappioahh theopeniiig disposed disposed at the end thereof. a on their loaclisandiii this position, delivery These and other"obje'cts and advantags is exceedingly 'dithcult as the pigwill pass of the invention will be fully set forth in the delivery opening and the crown of its the following description made in connechead will be in the adjacent bone of the sow. tion with the accompanying drawings in The hook or bent portion 8 of the end porwhieh like reference characters refer to the tion 2 has been found to be exceedingly same parts throughout the different views, elficient for insertion into the vaginal duct in which for turning the pigs laterally or turning the same on the longitudinal axis of the body so that the pig will be disposed on its belly. The pigs nose will then start through the opening. If the pig is presented head first for delivery, the forceps are held by the handles 1 and 2 and the jaws 6 and 7 inserted into the sow. The blade 6 is manipulated to be positioned in the mouth of the pig and under the tongue so that the tongue will not be out or injured. The under jaw bone of the pig is V-shaped and the jaw 7 of the forceps will be disposed under this lower jaw of the pig and in the recess of said bone. The portion 7 is disposed outwardly beyond the blade 6 on account of the fact that the pigs tongue is attached to the lower jaw in front of the fork of the jaw or the jaw bone, The hook 7 therefore must extend far enough so that it will hook into the jaw bone before the blade 6 presses against and injures the cord under the tongue. The inner surface of the blade 6 at its base curves into handle 3 to form an arch or concavity, as clearly shown in Fig. 1, to provide room for the pigs teeth so that the teeth will not be crushed. Vith the pig so engaged the same can be withdrawn and delivered without injury thereto and without injury to the sow. If the pig is presented rear end foremost, one or both of the legs of the pig can be engaged between the jaw 7 and blade 6 and a tight hold on the legs secured. The pig can then be drawn out and delivered without injury. The pointed hook 9 on the handle 1 is not novel and is somewhat like the common implement or hook often used by farmers or veterinarians for assisting in the delivery of the pigs when, as a last resort, it is desired only to get the pigs away whether dead or not. Such a hook, however, is unsuitable to be inserted far into the vaginal duct, as when this is done the sow is seriously injured.

From the above description it is seen that applicant has provided a simple and very eflicient tool for the purpose intended. The smooth round hook portion 8, while quite simple in construction, has been found to be very eflicient in turning over the pigs, as described. The formation of the jaws of the forceps has also proven exceedingly eflicient in practice. The tool has actually been made and used and the successful operation thereof fully demonstrated.

It will, of course, be understood that various changes may be made in the form, de-

tails and proportions of the parts without departing from the scope of applicants invention, which, generally stated, consists in a device capable of carrying out the objects above enumerated, such as shown and described and as set forth in the appended claims.

What is claimed is:

1. A pig delivery forceps having in combination, means for engaging the inside of the lower jaw of an undelivered pig beneath the tongue thereof, and an opposed blunt means pivoted to said first mentioned means and disposed centrally transversc-ly thereof for engaging the exterior of said lower jaw between the .sides thereof.

2. A pig delivery forceps having in combination, pivotally opposed members, one forming a blade tapering to a thin edge for engaging the inside of the lower jaw of the pig beneath the tongue and the other member formed as a blunt ended rod disposed centrally transversely of said blade and directed substantially at right angles thereto beyond the outer end thereof for engaging the pig at the exterior of the lower jaw and between the jaw bones.

3. A forceps fordelivering pigs and other animals, comprising two arms pivoted together, the grasping end of one of said arms being formed as a blunt-ended hook, the grasping end of the other of said arms being formed as a substantially flat thin blade, the outer end thereof being rounded and of greater width than the remainder of said blade, said blade being adapted to fit beneath the tongue of an undelivered pig, said hook end being positioned upwards and away from the outer end of said blade, whereby, when the blade member is inserted beneath a pigs tongue, the hook member may be made to grasp immediately behind the under jaw bone of the pig and a firm hold may be obtained by the co-operation of the forceps arms without injuring the 4. A forceps for delivering pigs and other animals, comprising a pair of jaws, one of which is in the form of a thin narrow blade having a rounded end and the other of which is in the form of a hook bent toward said blade and having a blunt end disposed outwardly of the end of said blade, said blade tapering in width from its outer end inwardly.

In testimony whereof I afiix my signature.
